Chemical protective garments are available in a wide variety of fabrics and designs that provide varying levels of protection for chemical process industries (CPI) workers, who may be exposed to chemicals in the form of vapors, liquids and particles. While other forms of personal protective equipment — such as safety glasses and hard hats — are highly regulated in the U.S. and Canada, the...

The pressure testing of process piping and vessels is essential in the chemical process industries (CPI). In liquefied natural gas (LNG) and other cryogenic facilities, residual water left by hydraulic pressure testing could result in operational problems if not completely removed, and complete removal of residual water can be very difficult and time consuming. Pneumatic pressure testing avoids these...

Although plant safety should be a top priority every day, there are certain times when extra vigilance is needed to make sure that safety practices are being maintained. This article outlines three periods deemed to be “critical” for plant safety and specific items to pay attention to in these periods.     Three critical periods The following three phases in a production plant’s...

History is a constant reminder that accidents and catastrophic events can and do occur in process environments. As processes become more complex (for instance, allowing for greater operating temperatures and pressures to be used) and existing basic process control systems (BPCS) and safety systems age, risk reduction becomes more challenging. Regulations from the U.S. Occupational Safety and Health Admin...

With productivity, growth and reliability as constant drivers, the proactive evaluation of all machinery is critically important. In order to gain useful insight, the maintenance team must capture comprehensive data related to machinery operation and carry out a logical interpretation of the data. The conventional language of equipment components — vibration — transmits relevant information...

When tanks are draining, the potential may exist for a swirling vortex to form leading from the liquid surface to any of the bottom-exit or side-exit nozzles connected to downstream piping (Figure 1). One important aspect of the vortex is whether it will entrain air or other gases into the discharge flow. Such vapor entrainment can lead to a host of problems, ranging from vacuum collapse of the supply...

Last month, two significant cracks were found in the cornerstones of conventional thinking about how chemicals in the environment make their way into the human body and other living organisms, possibly leading to damaging effects. The timing is particularly apropos, as the first registration deadline of November 30 approaches for the EU’s regulation on Registration, Evaluation, Authorization and...

As potential threats continue to make headline news around the world, it is clear that the need for security measures is an ongoing process, and that this process requires vigilance. The chemical process industries (CPI) are considered part of the critical infrastructure in the U.S., and as such are regulated by the U.S. Dept. of Homeland Security (DHS; Washington, D.C.; www.dhs.gov) under the Chemical...
